EXPERIMENTAL INVESTIGATION ON SELF COMPACTING SELF CURING CONCRETE WITH LIMESTONE POWDER AND STEEL FIBERS
Abstract
Self-Compacting concrete is a type of concrete that gets compacted under its self-weight. It’s commonly abbreviated as SCC and defined as the concrete which can placed and compacted into every corner of a form work; purely means of its self-weight by eliminating the need of either external energy input from vibrators or any type of compacting effort. In this study, the effect of replacing the cement by limestone powder with (5%,10%,20%) respectively and steel fibers (2%) their combinations of various proportions on the properties of Self compacting concrete has been compared. Properties of compressive strength, split tensile strength and flexural strength of Concrete were determined. However, the results of this study suggest that limestone powder (10%),steel fibers (2%) combinations can improve the workability of Self compacting concrete, more than conventional concrete and while their using separate. Limestone powder can have a
positive influence on the mechanical performance at early strength development while Steel fibers can improve more strength avoid cracking. Rapid chloride permeability test for conventional concrete and optimum one ie of replacement of cement by Lime stone powder (10%) and steel fibers (2%) with self compacting self curing concrete gets moderately so results suggest that we can use for construction purpose. For slab self curing is more workable than normal curing
